  1. Location Based MBS Service for IEEE 802.16- IP Push Service - 2007. 7. 23. Jongtaek Oh jtoh@hansung.ac.kr

  2. Contents • Motivation • Technical description of LB MBS • Killer applications for LB MBS • Proposed working method • New RFC on LB MBS over IEEE 802.16 Networks • References

  3. Motivation • Considering IEEE 802.16 radio system as; • Broadband wireless service system • Fixed Wireless Access or mobile communication system applications • Service convergence with IP network as core network • Competition with cellular network • Prominent prospects on Broadcasting and LBS • Necessity of new killer applications – Location Based MBS • Keeping existing protocols with additional functions in BS

  4. Limitations for Internet Broadcasting • Necessity of unique IP address • Not enough IP addresses to be assigned • Difficulty of managing IP addresses, especially for mobile unit • Client-server model : Client access & request to server. • Necessity of pre-knowledge of web site address of server (even multicasting IP address) • Every time click is needed to request information. • So much load to server and network as increasing number of users • Not enough solutions for broadcasting • Not enough solutions for user location information

  5. Benefits of LB MBS • No necessity of receiver IP address • No DHCP server • No IP address managing • No limitation of number of receivers • No necessity of pre-knowledge of web site address & information request • Just listening and tuning of broadcast data • Less load for broadcasting server • Sending datagram to each RAS not to terminals • Less traffic generation to network • No privacy problem of user location information • No violations to existing protocols !

  6. Network Configuration for LB MBS BS with IP2 AR Broadcasting server Internet BS with IP1 Unicasting MS Broadcasting BS :Base Station AR :Access Router MS :Mobile Station

  7. Control Message • Control field for broadcasting parameters of AR • Optional protocol between server and AR • repetition period, repetition duration, & priority control • authentication, scrambling, etc. • Type of data field • Message format between server and terminals • According to this, users can filter interesting data only. • Terminals can use for their own purposes. Control field type of data field broadcast data Simplified format of UDP data field

  8. Terminal Initiation for LB MBS timer 6) Quit after time out 3) Req. Broadcasting Broadcasting server AR BS Internet 4) Broadcasting data 5) Data Broadcasting 1) Broadcasting Announcement 2) Req. Broadcasting * This seems like multicasting protocol, but more simple, and no need of many multicasting addresses.

  9. Comparison of Network Traffic Conventional Unicasting method Total Traffic LB MBS method LB MBS with Terminal Trigger No. of Terminals ( No. of BSs)

  10. Broadcast HyperText, Graphic, Image, Sound, and even Alerting data FIRE Bus Stop Seoul City Tour EXIT * Special menu of nearby restaurant - Sea food spaghetti - Herb bibimbab - Original pizza - Hot cold noodle Korean Restaurant Nearby historic spot is …. Click ! Special price W5,000 Magic cap ESCAPE ! W50,000 Tour Bus Just click now! from just seeing into interactive service repeating This statue is ... Killer Applications

  11. Framework of Proposed New RFC on LB MBS over IEEE 802.16 Networks • Introduction • IEEE 802.16 network model for location based MBS service • Functional requirements for the network components • Message format for the location based MBS service • Optional triggering protocol • Application services of the location based MBS service • References

  12. References • Local Information Service Protocol using WLAN, TTAS.KO-06.0116, Oct. 20. 2006. • Report ITU-R M.[IP CHAR]:Key technical and operational characteristics for access technologiesto support IP applications over mobile systems, ITU-R WP 8A/WP 8F, May 2007. • A Scheme for Location-Based Internet Broadcasting and its Applications, accepted for publication in IEEE Comm. Mag., July, 2007.
